Abstract
The utility model discloses a wedge-shaped rubber coupling device for a lower floor rail vehicle. One ring of right rubber blocks are arranged on one end of an output axle of a transmission gear to achieve the first-level buffering, damping transmission; a ring of left rubber blocks are arranged on a star-shaped disk, the star-shaped disk is in transition connection with an output vehicle axle to achieve the second-level buffering, damping transmission. The drive torque is transferred, the deviation, the angle displacement and the relative movement between the output axle of the transmission gear and the output vehicle axle are absorbed, so as to completely satisfy the requirement for the top speed and the top torque on the performance aspect during the vehicle operation process. Two levels of the buffering still better bear vibration and impact generated by vehicle start, brake and the rail condition, thus the power of the low floor rail vehicle is stably transmitted and the noise is reduced.

Adopt technique scheme, with an end of driving gear output shaft, the right block rubber of a circle is set, to reach first order buffering, damping transmission; With the left block rubber of a circle also is set on the star-like dish, star-like dish is connected with the transition of output axletree again, to reach second level buffering, damping transmission; Can not only realize the transmission of driving torque; And can absorb the relative movement between deviation, angular displacement and gearbox output shaft and the axletree; Maximum (top) speed when on performance, fully satisfying vehicle operating, peak torque requirement; Two-stage buffering also can better bear launch train, braking and since vibration and the impact that the track condition produces make and the steady transmission of power of low-floor track train reduce noise.
In technique scheme, evenly be provided with 6 wedge shape boss on the excircle of said installation disk, form 6 wedge slots thus, wheel is installed on this right side and left side installation wheel is gone up by being evenly distributed in 6 installation petals, and stagger in the position of said installation petal and wedge shape boss.
In order to increase the working life of shaft coupling, said right block rubber adopts heat resistant rubber to process.
In technique scheme, said right block rubber connects into a sector structure by plurality of partitions, connects rubber between adjacent two dividing plates, and the periphery of said dividing plate wraps up with encapsulate.
In technique scheme, said dividing plate is made of aluminum.
Beneficial effect: the effect that the utility model is reasonable in design, simple in structure, enforcement is easy, have transmitting movement and power, the effect of playing the balance transmitting torque, its absorbed oscillation impact effect is splendid, and can reduce noise; Axle direction is short, saves the space; Installation is easy to the heart, exempts from maintenance.
